Description
If I understand the intention of this feature correctly, the boundingVolumePositionAttribute is used to provide a reduced set of vertices to speed up the calculation of the bounding volume. When the attribute is set on geometries with indexBuffers the function calculateLocalBoundingVolume incorrectly mixes the boundingVolumePositionBuffer and the original indexBuffer (that references into the vertexBuffer). This cannot work and will crash the application.
